Vegetation indices

Developing and assessing vegetation indices:

The recently-developed SpecNet index, the Chlorophyll/Carotenoid Index (CCI), offers improved tracking of GPP phenology (relative to NDVI, NIRv).

In evergreens, the strong CCI-GPP relationship is driven by seasonal changes in pigment pool sizes.

CCI also works as a GPP indicator in deciduous and annual vegetation.

Seasonal changes in CCI and pigment pools appear to be closely related to chlorophyll fluorescence (and potentially SIF).
